Description

  The present invention generally relates to the field of vaporizers for consuming plant materials such as tobacco, and more particularly to using a portable self-contained vaporizer that releases volatile components sufficiently without burning. It relates to an apparatus and a method.

  Because tobacco is generally consumed by igniting tobacco, consumers are forced to inhale the combustion products along with any volatile components such as nicotine present therein. Because combustion products can be harmful, inhalation of burned tobacco can cause undesirable health effects.

  One way to avoid inhalation of combustion products is to heat the cigarette to a temperature sufficient to release its volatile components without burning. Prior art devices, often referred to as “vaporizers”, generally employ a continuous heating source such as a flame using butane fuel, a catalytic burner using butane fuel, or an electrical resistance heater. The heat source of many such devices is in conductive contact with a cigarette or receptacle containing the cigarette. As a result, the temperature becomes high and the surface of the cigarette near the heat source may burn and carbonize to the inside.

  Further, in many prior art vaporizers, if both the cigarette itself and the material holding part are not heated to a desired temperature, the vapor of the volatile substance cannot be extracted.

  In addition, because heating is generally performed continuously rather than on demand, many existing vaporizers are inefficient to use power, which keeps the elevated temperature constant. This is because they often provide heat to hold, which does not correspond to the duty cycle of intermittent inhalation of the product vapor intended by the user.

  One embodiment of the present invention overcomes the disadvantages of the prior art by providing a vaporizer that fully houses the material to be consumed.

  Other embodiments of the present invention overcome the shortcomings of the prior art by providing a vaporizer having an upper portion that can be removably installed over the lower portion to accommodate tobacco. In one embodiment, the upper and lower portions are held in place with magnets.

  Yet another embodiment of the present invention overcomes the disadvantages of the prior art by providing a closed vaporizer having a window for viewing the tobacco contained therein. In one embodiment, the window also reveals the extracted steam and red heat from the heating element.

  One embodiment of the present invention overcomes the disadvantages of the prior art by providing a closed carburetor where red heat from the heating element is also visible from the inlet.

  Other embodiments of the present invention provide a vaporizer that has a heating element that is supported floating in a transparent heating chamber that can transmit light generated by the heating element of the instrument. To overcome the disadvantages of the prior art.

  Yet another embodiment of the present invention provides a closed vaporizer having a heating element that is integral with a material chamber and supported in a floating manner in a concentric transparent heating chamber. Overcoming the shortcomings of the prior art.

  One embodiment of the present invention includes a computer controlled temperature regulation system that allows proper vaporization temperature.

  Another embodiment of the invention includes a vaporizer having a rechargeable battery that can be removed by a user.

  One aspect of the present invention is to provide a vaporizer for supplying steam from plant material to a user, and the plant material may be tobacco. The vaporizer includes a housing, and a heater substantially within the housing includes an electrical energy storage device, a switch operable by a user, a heating element, an electrical energy storage device, and a switch operable by the user.

The user therefore activates a switch operable by the user and inhales air outside the vaporizer by inhaling from the exhaust, followed by heating the air in contact with the heating element to the heated air temperature. Then, the plant material is at least partially vaporized with heated air, and then at least a portion of the vaporized tobacco is supplied to the user through the exhaust vent.

  Another aspect of the present invention is to provide a method for supplying steam of plant material using a vaporizer. The method comprises manually operating the vaporizer, the electrical energy stored in the vaporizer, the receptacle for receiving the plant material, and the stored electrical energy from the inlet receiving air. A fluid passage extending through a manually actuable heater for heating the fluid, through the receptacle and to the outlet, and sucking from the outlet. Therefore, air is sucked into the passage from outside the vaporizer, and subsequently its air temperature rises in the heater, heats the plant material, extracts steam from it, and supplies this steam to the user .

Reference is made to FIG. 13, which is a schematic diagram of one embodiment of the electronic components in the vessel.

  FIGS. 11 and 12 illustrate the set of cigarettes M on the bowl 640 and the flow of air and steam through the vaporizer 100. Specifically, FIG. 11 shows the upper portion 210 removed from the lower portion 220. This configuration provides access to the bowl 640 for cleaning and setting a new cigarette M, as well as cleaning the inner surfaces 601 and 611, the recess 615, and the window mount 631.

  When the upper portion 210 and the lower portion 220 are assembled as in FIG. 1, the recesses 615 and 635 form an air passage between the flange 640 and the opening 607. Specifically, FIG. 11 shows that portions of surfaces 601 and 604 that contact surfaces 611 and 633 (shown as 601a) control or block the flow of air. Other parts of 604 do not contact the recesses 615 or 635 (shown as face 601b) and therefore provide a passage for air flow. Therefore, as indicated by the arrows, the air flow enters the inlet 105, rises through the bowl 640 and the opening 605, and passes between the upper portion 210 and the lower portion 220 along the surface 601b. , Through the opening 607 and then through the opening 501.

Enters, reaches the opening 607 along the surface 601, and passes through the opening 311 of the mouthpiece 103.

  FIG. 13 is a schematic diagram 1300 illustrating the control electronic component 720 of the vaporizer 100. Thus, for example, but not limited to, schematic diagram 1300 is a connection of power switch 201, pushbutton switch 109, indicator lamp 307, battery 731, programmable processor 725, power controller 727, temperature sensor 942, and heating element 715. Indicates.

  In addition to providing temperature control for the tobacco vaporization process, the control electronics 720 also provides overheating of the vaporizer body and internal components and thereby damage to the battery, computer or other internal components. Can be prevented.

  The processor 725 receives power from the battery 731, receives input from the power switch 201, the push button switch 109, and the temperature sensor 942, supplies power to one or more display lamps 307, and supplies a signal to the power controller 727. To be programmed. The power supply controller 727 receives a command signal from the processor 725 for supplying power to the heating element 715 from the battery 731.

  The power switch 201 has two or more setting positions, for example, an “off” setting position and an “on” setting position, or an “off” setting position, a “low temperature” setting position, and a “high temperature” setting position. Also good. When the power switch 201 is in the “off” setting position, the power to all the electronic components in the vaporizer 100 is turned off. When the power switch 201 is in the “on”, “low temperature”, or “high temperature” setting position, the processor 725 stores the corresponding stored on temperature (TON), low temperature (TL), or high temperature (TH). These are target temperatures for controlling the temperature measured by the temperature sensor 942. As described above, the temperature sensor 942 measures the temperature of the air just before the heated air flows through the bowl 640.

  Indicator lamp 307 may include a lamp programmed to indicate the operation of vaporizer 100. Thus, for example, but not limited to, the indicator lamp 307 is a weak green lamp that is powered to indicate that the vaporizer 100 is powered on at the low temperature setting position, and the vaporizer is at the high temperature setting position. A bright green lamp that is powered to indicate that it is powered on, a flashing blue lamp that indicates that the vaporizer is charging, and a red that indicates that the battery is low The lamp may include a dark red lamp to indicate that the device has overheated and was automatically turned off.

  In addition to this, when the power switch 201 is in the “on”, “low temperature”, or “high temperature” setting position and the push button switch 109 is pressed, the processor 725 supplies power to the power controller 727 from the battery 731. Send a signal to the element 715 to supply. In certain embodiments, the processor 725 uses a control algorithm such as a PID control algorithm to power the heating element 715 such that the temperature T measured by the temperature sensor 942 is held at the temperature indicated by the power switch 201. To do.

Of course, the operation of the vaporizer 100 may be optimized depending on the desired vaporization temperature. Therefore, the target temperature of temperature sensor 942 is selected to effectively release volatile materials from tobacco or other plant material of interest. Without limiting the application of the present invention, Table I shows the effective vaporization temperatures of some plant materials classified into low, medium, or high temperature groups of vaporization temperatures. It will be appreciated that these classifications are for reference only and that each material may have a range of vaporization temperatures, which may span different classifications. Thus, for example, tobacco can range from low, medium and high depending on the number and type of volatiles found in the tobacco. The vaporizer 100 allows the user to control the method of vaporizing the plant material according to the temperature setting of the vaporizer 100.

  In general, the target temperature measured by the temperature sensor 942 ranges from 145 ° C. to 205 ° C., for example, but not limited to, about 145 ° C., 150 ° C., 155 ° C., 160 ° C., 165 ° C., 170 ° C., It may be 175 ° C, 180 ° C, 185 ° C, 195 ° C, 200 ° C or 205 ° C. For a plurality of temperature settings such as “low temperature” and “high temperature”, the low temperature setting is suitable for vaporizing volatile substances at low temperatures such as cigarettes, and the temperature range is in the range of 150 ° C. to 165 ° C. May be, for example, 150 ° C., 155 ° C., 160 ° C. or 165 ° C. The high temperature setting is suitable for vaporizing volatile substances at a high temperature such as ginseng, the temperature may be 190 ° C. to 205 ° C., and the numerical value may be 190 ° C., 195 ° C., 200 ° C. or 205 ° C., for example.

Example of use of vaporizer The following is an example of a user of the vaporizer 100. 1 and 3, when the power switch 201 is in the “off position”, the user grasps the lower portion 220 with one hand and places its thumb in the recess 309 to remove the upper portion 210. With reference to FIG. 6, the user can then clean the various inner surfaces and hooks 640 and place a fresh sample of plant material in the hooks. Thereafter, the upper portion 210 can be securely placed on the lower portion 220.

  As shown in FIGS. 6 and 7, the user can always see the presence of plant material as viewed from the window 107.

  Next, the user switches the power switch 201 to an appropriate setting other than “off” (for example, “on”, “low temperature”, or “high temperature”).

  Next, the user presses the push button switch 109. Within a few seconds, the control electronics 720 are supplied with sufficient power to raise the air near the temperature sensor 942 to the target temperature. Red heat from the heating element 715 may be visible by the user through the window 107 and / or through the inlet 105. For certain plant materials, the extracted steam can also be seen through the window 107.

  When the proper temperature is visually displayed, the user can inhale from the mouthpiece 103. Then, air is drawn into the air inlet 105, passes through the passage 713, passes through the plant material in the bowl-shaped portion 640, passes between the groove 635 and the surface 601, enters the opening 607 along the surface 601. Then, it reaches the user's mouth through the opening 311.

  Most of the power supplied to the heating element 715 heats the air in the passage 713, and therefore the plant material in the bowl 640 vaporizes convectively as hot air flows through the plant material. .

  The surface that comes into contact with the heated air as it flows between the surface 601 and the upper portion 210 functions as a “heat sink”, whereby the gas is cooled from the high temperature of the heating element 715 to approximately room temperature. After inhalation, the user releases pushbutton switch 109, thereby reducing the power through heating element 715.
